EYELETINGJVIAHINE.

Specification of Letters Patent.

Patented Nov. 1o, 1914.

To all whom it may concern:

Be it known that I, Ronnnr B. SMITH, a citizen of the United States, residing at Quincy, inthe county of `llorfolk and State of Massachusetts, have invented certain lniproifements in EyeletingMachines, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the draw ings indicating like parts in the several figures.

This invention relaties to machines for setting fasteners such, for example, as eyelets; and it pertains more particularly to improved means for setting fasteners of various shapes in predetermined positions in the stock. i

It is frequently necessary to set fasteners which are non-circular or unsymmetrically shaped in predetermined positions inthe stock. In setting oval eyelets in boots and shoes, for instance, it may be required that the long axis of the oval should be parallel, or in other angular relation, with the edge of the lacing slit. Ordinarily machines for setting fasteners are provided with. feeding devices which deliver the fasteners in the proper position to be set in the stock, that is, with their dimensions disposed in that relation to the stock whichv lthey are intended finally to have when set. rThe setting devices of such machines have been adapted merely7 to set fasteners in the prem-ranged position determined by the feeding devices. This is well exemplified in a familiar type of machine wherein feeding devices deliver fasteners in succession in axial alinement with 'i devices might be adapted to deliver the fas teners in the required position. Such a change in the feeding devices would involve considerable inconvenience and, in fact, the

general organisation of most machines would notvpernnt changes in the feeding devices of sutlicient scope to provide for setting fasteners in many positions which might be desirable.

lilith these considerations in view it is an object of the present invention to obviate difficulties of this sort by permitting any desired form of feeding device to cooperate with means for receiving fasteners from the feeding devices and arranging them in a de` sired position which may be different from the position determined by the feeding devices.

In this connection an important feature of the invention comprises the combination of feeding devices and setting mechanism including means for receiving a fastener from the feeding devices and changing its position prior to the setting operation.

.tin object of the invention is to provide an improved and simplified device or mechanism for carrying out the. latter functions in adirect and uniform manner and preferably without the employment of moving parts. A preferred embodiment of this feature consists in a machine for setting eyelets, having `a raceway for delivering eyelets to the setting mechanism, which mechanism in cludes a tapering, and preferably spiral, spindle for :receiving the eyelets from the raceway and turning them through the proper angle into the desired position for setting. l y

rlhe preferred embodiment just referred to constitutes the subject of the detailed de` scription hereinafter set forth for purposes of illustration, but it is to be understood that this invention is not limited in the scope of its application 'to use in connection with this specific embodiment or in connection with machines of the saine type.` rlhe accompanying drawings represent portions of a machine of the general type shown in `United States Patent No. 606,964, granted July 5, i898. Enough of such a machine is show and described herein to make `clear its `operation in connection with the improveroo 2 is a plan view of the lower set and spindle; Figs. 3 and 4 illustrate successive steps in the operation of the machine; Fig. 5 is a view in perspective of part of the lower set and spindle.

The frame 2 of the machine is provided with the vertical retaining portion 8 in which is rigidly mounted the upper set 10. This set is of oval shape and is positioned in the machine with its longer diameter parallel to the edge of the work to be eyeleted. A pilot hole 11 is provided in the end of the set for a purpose to be hereinafter set forth.

Located in alinement with the upper set 10 is the lower set 14 which is mounted in the movable retaining member 20 as shown in Fig. t. The member 20 is bored to receive the reduced portion of the set and provided with a pocket for the reception of the compression spring 13 which bears against a button 17 fast on the end of the cylindrical shank 15 of the spindle 12, whereby the spindle is normally held upwardly in the position shown in the drawings. The retaininfr member 20 is mounted for vertical reciprocation in the frame 2 and is connected with suitable actuating means by the lever 19 whereby it is moved bodily upward for setting an eyelet.

A raceway 4 mounted on one side of the frame 2 is actuated by the lever 5 to advance: in a iixed path and deliver oval eyelets 40 successively to the spindle 12 and is moved rearwardly into an inoperative position after delivering each eyelet. The sprinur actuated detent 6 is pivoted near the end o? the raceway and serves to retain the eyelets in the raceway but permits the lowest eyelet to be drawn out by the set V12 when the raceway is moved back from the position shown in Fig. 1.

The spindle 12 is of such a shape that when an oval eyelet is delivered to its upper end with its major diameter perpendicular to the edge of the Work, the eyelet is turned atright angles as it slides down the spindle and when the set is reached it tits into the depression 1G with its major diameter parallel with the edge of the work. This result is accomplished by the action of the spindle on the inner surface of the eyelet. The spindle 12 is preferably made tapering and slightly spiral in shape and of such dimensions that the major diameter of the upper end of the spindle is shorter than the minor inside diameter of the eyelets to be set, while the major diameter of the spindle at its base is longer than the minor inside diameter of the eyelet but shorter than its major inside diameter. It will be apparent that in order to pass down a tapering spindle of the dimensions above set forth an oval eyelet must turn into a posi- I tion in which its major diameter is parallel the raceway as shown in Fig. 3. The raceway is then retracted and the spindle draws the eyelet out of the raceway, the mlajor diameter of the eyelet being still perpendicular to the edge of the work 9. As soon as the eyelet is clear of the raceway it slides down the spindle under the influence of gravity and is turned into the position shown in Fig. 4 during this step. After the raceway has been moved out of alinement with the sets, the lower set 1-1 continues to rise, carrying the eyelet into the work and meeting the upper set 10 with which it co'- operates to set the eyelet. The spindle 12 has meantime engaged the pilot hole 11 in the upper set and is forced downwardly against the spring 13 into the set 14 where it remains during the setting operation.

n the construction herein shown and described the raceway makes approximately a right angle with the edge of the work and accordingly each eyelet has imparted to it a quarter turn. It will be apparent, how-- ever, that itis immaterial at what angle the racewa f delivers the eyelets to the spindle since tie final position will be the same in every case.

It will also be clear that my invention may be embodied equally well in a manually operated or in a power machine.

Having described my invention what I claim as new and desire to secure by Letters Patent is:
